Liquid detergent formulation containing peroxide and a metal-based bleach catalyst

Abstract

A stable, liquid bleach composition is disclosed. The composition comprises a peroxide-based bleaching agent, water, a metal catalyst, and a polyol. The polyol is a secondary solvent that promote peroxide stability in the presence of a catalyst.

We claim: 
     
       1. A stable liquid cleaning composition comprising:
 a) a hydrogen peroxide component; 
 b) a manganese catalyst; 
 c) glycerin; and 
 d) water, wherein the ratio of glycerin to the total amount of said glycerin and water is 0.25 to 0.35. 
 
     
     
       2. A liquid cleaning composition comprising:
 a) a peroxy component; 
 b) a metal-containing bleach catalyst; 
 c) a polyol which lies within a sphere in the Hansen space, defined by a radius R=6 (MPa) 1/2  or less; and 
 d) water, wherein the ratio of said polyol to the total amount of said polyol and water is 0.25 to 0.35. 
 
     
     
       3. The composition of  claim 1  wherein the peroxy component is hydrogen peroxide. 
     
     
       4. The composition of  claim 1  wherein the peroxy component is a stabilized hydrogen peroxide composition. 
     
     
       5. The composition of  claim 1  wherein the metal is selected from the group of transition metals consisting of Mn, Co, Fe, or Cu. 
     
     
       6. The composition of  claim 1  wherein the metal is Mn. 
     
     
       7. The composition of  claim 1  wherein the polyol is glycerin, sorbitol, xylitol, mannitol, trihydroxy butane, tetrahydroxy pentane, or ethylene glycol and mixtures thereof. 
     
     
       8. The composition of  claim 1  wherein the polyol is glycerin. 
     
     
       9. The composition of  claim 1  further comprising a surfactant. 
     
     
       10. The composition of  claim 1  wherein the weight percentage of said catalyst is 0.2 to 2% of the overall composition.
